# Key Concepts As part of using our APIs and SDKs there are a few key concepts that you should be familiar with. These are described in more detail in the subsequent pages. Don't worry if you miss something - we try to point to these as we talk about them in the actual documentation. If you think we're missing something, feel free to message us in your Slack channel if you're a customer or reach out to our support team at ! --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.peoplelogic.dev/guides/key-concepts.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
